No way to detect knob change without polling in onTick

[boourns]

1 - there is no callback or way to know when a knob is turned except for registering onTick and comparing values.

We can't detect changes and emit MIDI if transport isn't running.

Options:

• onChange(name) when a value changes, called from process
• ability to register a timer
• change onTick to call regardless of transport state

what could get abused? onChange when there's tons of knobs could slow shit down a lot. maybe we call it once with a list of parameters that changed this time slice?

onChange(parameterNames)

2 - someone else updating a value re-renders a ton of shit on other users
